I get what you’re saying, but the eating and the spiciness of the wings actually contribute to the quality of the interview.
-
Eating a meal with someone is disarming and contributes to the relaxed, ungaurded nature or his guests.
-
Consuming spicy food, particularly extremely spicy food or spicy food in great quantity releases endorphins which.
So while yes the eating/reacting to how hot the sauce is does interrupt the flow of the interview somewhat, it does help him get good/candid answers for his guests.
So while his research team is outstanding and he’s a talented interviewer in his own right. The hot wings do serve a role in the interview as more than a clickbaity gimmick.
The comp for an older generation is cars. Cars saw similar growth and adoption in the 50s-80s. And they had similar growing pains, reliability and maintenance issues were common place. So being able to perform maintenance and having an understanding of how they work was far more wide spread than just hobbyist and professionals.
As cars advanced the need to perform field maintenance and ad hoc repairs became less required so future generations (on average) became less knowledgeable and skilled at various car repair (and modification) activities, because cars just work now so there’s really no need to worry about learning how to fix minor issues, because they’re just not a common problem.
